RIDING ATTACHMENT FOR HARROWST Application filed January 28, 1907.

To all whom it may concern:

Be it known that I, WILLIAM E. JOHNSON, a citizen of the United States of America, and resident of Rock Island, Illinois, have invented a certain new and useful Improve ment in Riding Attachments for Harrows, of which the following is a specification.

My invention relates to riding attachments for harrows or other similar agricultural implements. Prior to my invention, these riding attachments have been of such character that lateral side swing of the same causes the driver to be turned away from the harrow, so that he would no longer face the same. Furthermore, the construction was such that the striking of stones or other obstructions by the wheels of the riding attachment subjected the rider to a constant twisting or turning motion, which was not only unpleasant and annoying, but which also tended every now and then to turn the driver partially around, so that he would no longer face the harrow.

Generally stated, the object of my invention is the provision of an improved arrangement which will permit the riding attachment to swing laterally, and which will yield to stones or other obstructions that may strike one or the other of the two wheels, without twisting or turning the driver partially around, thus insuring an arrangement in which the driver will always face the harrow, and by which he will be subjected to less annoyance than heretofore.

To the foregoing and other useful ends, my invention consists in matters hereinafter set forth and claimed.

In the accompanying drawings, Figure 1 is a plan of a harrow and a riding attachment therefor embodying the principles of my invention. Fig. 2 is a similar view showing the riding attachment swung laterally relatively to the harrow. Fig. 3 is a detail sectional view on line 33 of Fig. 1. Fig. 4 is a section on line 44 in Fig. 1. Fig. 5 is an enlarged rear elevation of the means by which the drivers seat is mounted on the axle. Fig. 6 is a detail section on line 6 6 in Fig. 5. Fig. 7 is a perspective of the looking bolt by which the seat is locked to the axle-that is to say, the bolt by which the seat-spring is yieldingly locked at right angles to the said axle.

As thus illustrated, the harrow A may be of any suitable or known construction, and may be provided with hand levers a for con- Specification of Letters Patent.

trolling the teeth thereof. The axle B of the riding attachment is connected by crossed draft rods C with the forward portion of the harrow, said rods being pivotally attached at their opposite ends. Said axle is provided with supporting wheels D, and has a turn table or swivel connection E secured to its middle portion. This turntable is composed of the lower portion e which is secured to the axle and the rotatable upper portion e which is secured to the said lower portion by the bolt or pivot 6 v The said lower portion carries a spring-pressed bolt 6 having a tapered or wedge-shaped engaging portion 6 adapted to engage a correspondingly shaped notch e in the upper portion 6 The seat-spring F has a drivers seat f at its upper end, and has its lower portion f rigidly secured to the upper portion 6 'of the turn-table. In this way the seat-spring is adapted to be yieldingly locked at right angles to the axle. The portion 6 has a forward portion 6 to which is secured, a bar 6 This bar has its forward end provided with a foot-rest e which can be adjusted relatively to the seat by means of the bolt-holes e in the bar and the bolt 6 A similar bolt and row of bolt-holes in the upper portion of the seat-spring permits the seat to be adjusted toward and away from the foot-rest. The said bar 6 also carries a bracket 6 provided with slots 6 and 6 through which extend the draft rods C, as shown more clearly in Fig. 3. With this arrangement, the riding attachment can swing to one side, as shown in Fig. 2, but at the same time the driver will still squarely face the harrow. When a stone or other obstruction strikes one of the wheels D, the locking bolt 6 disengages the portion e and thus permits the engagement of the rods C with the bracket 6 to hold the seat f against turning with the axle B'. In this way, the driver will always squarely face the harrow, and yet the riding attachment is free to swing laterally when the harrow is turned around. The crossed draw bars of them selves ought and do perform the principal duty of maintaining the axle in a parallel position to the harrow evener bar, when the entire mechanism is being drawn straight ahead, and yet permits the angling of the axle relative to the evener of the harrow, or the harrow proper, when turns are being made. This automatic locking device, as shown in Fig. 6, is not an absolutely essential element'in the proper action and performance of this device, i. 6., to say the spring plunger could be dispensed with and a fairly satisfactory device result. This is possible, owing to the fact that the seat is controlled by the bar 6 being slidingly connected to the draw-b ars, but owing to the resiliency of these draft-bars and the more or less giving of the joints, there would be a constant backward and forward movement of the axle out of a parallel position with the harrow, when one wheel or the other would come in contact with an obstruction, such as a slight depression or elevation in the ground, a stone or a hard clod of earth. To avoid this, the auto matic locking device is provided, which will stiffen the structnre or the axle against oscillation under that condition, but which will automatically break or unlock as the harrow is turned.

What I claim as my invention is:

1. In a riding attachment for harrows, the combination of an axle, wheels for said axle, crossed draft rods for connecting the axle with the harrow, a seat swiveled on the axle, and means engaging the draft rods to prevent the seat from twisting with the axle.

2. In a riding attachment for harrows, the combination of an axle, wheels for said axle, a draft connection between the axle and the harrow, a seat yieldingly locked on the axle, and means extending forward and engaging said draft connection to prevent the seat from twisting with the axle.

3. In a riding attachment for harrows, the combination of an axle, supporting wheels for said axle, a seat swiveled on the axle,

. means for yieldingly locking the seat to the axle, means for connecting the axle with the harrow, adapted to permit the axle to twist relatively to the harrow, and means for prevepting the said seat from twisting with the ax e.

4. In a riding attachment for harrows, the combination of a wheeled vehicle, means for connecting the vehicle with the harrow,

adapted to permit the wheels of the vehicle to twist relatively to the harrow, a seat yieldingly locked to the axle and means connected with the vehicle to keep the rider facing the harrow.

5. In a riding attachment for harrows, the combination of an axle, wheels for said axle, a draft connection between the axle and the harrow, a seat swiveled on the axle, and means extending forward and slidably engaging said draft connection to prevent the seat from twisting with the axle.

6. In a riding attachment for harrows, the combination of a wheel and vehicle, a seat carried by said vehicle, draft rods connecting said vehicle to the harrow, and means through which said rods are adapted to pass for keeping the occupant of said seat squarely facing the harrow.

7. In a riding attachment for harrows, the combination of a wheel and vehicle, a seat carried by said vehicle, draft rods connecting said vehicle to the harrow, and a guiding bracket through which said rods are adapted to pass for keeping the occupant of said seat squarely facing the harrow.

8. In a riding attachment for harrows, the combination of a wheel and vehicle, a seat carried by said vehicle, draft rods connecting said vehicle to the harrow, and a double slotted guiding bracket through which said rods are adapted to pass for keeping the occupant of said seat squarely facing the harrow.
